Problems solved by technology

[0003] Due to the relatively high chlorine content of waste incineration fly ash, although the direct injection into cement kiln disposal method is simple and feasible, the chlorine content index of cement products is strictly limited, and the high chlorine content of materials entering the kiln seriously threatens the operation safety of cement kiln equipment. The amount of disposal is very small, which is far from meeting the demand for waste incineration fly ash disposal

Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] see figure 1 , Fly ash water desalination is the pre-process of co-processing fly ash in cement kilns. The fly ash is desalted through three-stage countercurrent water washing to reduce the chlorine content in the fly ash. The eluted fly ash then enters the disposal terminal, such as Cement kilns, ceramsite kilns, etc., can effectively reduce the impact of chlorine on the stable operation of the disposal terminal, and increase ...

Description

technical field [0001] The invention belongs to the technical field of cement kilns, and in particular relates to a fly ash water desalination system. Background technique [0002] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: [0003] Due to the relatively high chlorine content of waste incineration fly ash, although the direct injection into the cement kiln is a simple and feasible method, the final product of cement has strict restrictions on the chlorine content index, and the high chlorine content of the materials entering the kiln seriously threatens the safety of the cement kiln equipment operation. The amount of disposal is very small, which is far from meeting the needs of waste incineration fly ash disposal. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is to provide a fly ash water demineralization system that increases the water washi...
